Renal Biopsy A kidney biopsy (also known as a renal biopsy) is an important test to diagnose kidney disease and to monitor kidney transplants. A biopsy is a very small sample, which is used to examine kidney structure in minute detail. Urea and Creatinine Creatinine is a protein produced by muscle and released into the blood. The amount produced is relatively stable in a given person. The creatinine level in the serum is therefore determined by the rate it is being removed, which is roughly a measure of kidney function. If kidney function falls (say a kidney is removed to donate to a relative), the creatinine level will rise. Normal is about 1 for an average adult. Infants that have little muscle will have lower normal levels (0.2). Muscle bound weight lifters may have a higher normal creatinine. Serum creatinine only reflects renal function in a steady state. After removing a kidney, if...
